A species is declared extinct after exhaustive surveys of all potential habitats eliminate all reasonable doubt that the last individual of a species, whether in the wild or in captivity, has died. [15] Recently extinct species are defined by the IUCN as becoming extinct after 1500 CE. [1]
This page features lists of species and organisms that have become extinct. The reasons for extinction range from natural occurrences, such as shifts in the Earth's ecosystem or natural disasters, to human influences on nature by the overuse of natural resources, hunting and destruction of natural habitats.
As of 2022, the International Union for Conservation of Nature (IUCN) listed 40 animal species as extinct in the wild. [1] That is approximately 0.04% of all evaluated animal species.

A scarcity of reliably dated megafaunal bone deposits has made it difficult to construct timelines for megafaunal extinctions in certain areas, leading to a divide among researches about when and how megafaunal species went extinct. [113] [114] There are at least three hypotheses regarding the extinction of the Australian megafauna:
